This invention relates to the classof curtains, shades and screens andpertains particularly to. a screen designed primarily for window use.

The primary object of the present invention is to provide a windowscreen adapted to be mountedupon the window sash and adapted to besecured to the lower portion of the frame in such manner that the windowsash can be raised or lowered as :desired without the necessity of theoperator of the window moving or adjusting the screen, the screenautomatically adjusting itself to coverV the opening made by the raisingof the window sash.

Another object of this invention is to provide, in a manner ashereinafter set forth, a roll-up window screen operating with the sashof the window to which it is attached so that when the sash is loweredthe screen will be completely rolled and arranged beneathr a protectivecovering or shield, carried bythe window sash, above the screen. In thismanner, with a screen of the character embodying the' present invention,when the window sash is closed the view through the window is notobstructed by a screen extending thereover, the screen being rolledbeneath a protective shield.y

Another object ofthe invention is to provide a roll-up window screen sodesigned that it maybe readily applied to or removed from a window sashwithout the use oftools.

'A further object of this invention is to provide a roll-up screen ofthe above described character,` which will be of strong and durableconstruction easy to install and comparatively inexpensive tomanufacture.

The invention will be best understood from f a consideration of thefollowing detailed description taken in connection with the accompanyingdrawings forming a part of this specification, with the understanding,however,'that the invention is not confined to any strict conformitywith the showingof the drawings but may be'changed or modified so longas such changes or modifications mark no material departure from thesalient features ofthe invention as expressed in the appended claim.

. Referring to the drawings in detail where- 1n like numerals ofreference indicate `corresponding parts throughout, the numerals 1 and 2indicate the side members' and the sill respectively of a window frame,the lower sash thereof being shown in raised position and indicated bythe numeral 3.

The present invention comprises a pair of bracket` members 4 each ofwhich comprises` the side plate 6 having the laterally projecting f0ot7by means of which the bracket is secured to the outer face of a lowerrail of l the window sash 3.v The plate of the bracket 4 is providedwith a square slot 8 to receivel the square end 9 of a spring controlledroller 10, the plate portion of the bracket 5 being Aprovided with anapertureV (not shown) for the reception of the usual trunnion pin in theother end of the roller. This roller is similar to the well known windowshade roller and is supported atV its endsl in the samemanner, spring ofthe rollerbeing shown at 10a in Figure 3a. Y

Each of the Vbracket plates 6 has the forvward end thereof formed toprovide the tapered tongue 11 and, when the plates 4 are in position,there is mounted between these tongues a roller 12.

Secured to and roller about the springcontrolled roller 10 is a wirescreen fabric 13 the upper plate and has projecting upwardly therefromand ext-ending throughout the length thereof, the plate member 16. Thescreen extends across the outer face of this plate 16, in the mannershown. inwardly of each end of the plate 15 there is formed a pair oftransversely extending loops 17 and 18 through which there extends,longitudinally of the plate 15, a bolt 19. The inner end of each bolt isformed to set up a finger hold 20 and surrounding each holt, between theloops, is a coil spring 21, one end of which engages the outer loop, orthe loop 17, while the other end is secured to the bolt as indicated `at22. As will be readily understood from Fig. 3, the bolt at each side ofthe screen is designed to engage in appropriate receiving recesses inthe adjacent portion of the window frame. It will be readily seen thatby drawing the bolt handles 20 toward one another the bolts willdisengage from the window frame to permit the raising of the screenwhile the window sash is in raised position.

The inner face of each side frame 1 of the sash is provided with thelongitudinally eX- tending angled member or sealing strip 23, one flangeof which is secured against the frame to cause the other flange toproject from the face thereof against the outer face of the screenfabric at one side edge thereof. When the fabric is drawn down the sideedges will bear against the back of this inwardly extending portion ofthe adjacent angled member as will also the ends of the plate 16 and anyspace formed between the edge of the fabric and the adjacent frame willbe covered to prevent the entrance of insects. The roller 12, over whichthe fabric is drawn when unrolled from its supporting roller, is spacedjust far enough from the inner faces of the inwardly projecting portionsof the angled members to permit the screen to pass therebetween, thusacting to hold the screen against these members.

Secured to the outer face of the lower rail of the window sash above thescreen roller is a downwardly curving hood 24 which, eX- tends acrossand protects the screen and the rollers. The inner edge of the hood 24has the flange 25 formed there-along for attaching the hood to the sash.As shown in Figure 2 the hood projects outwardly just far enough topermit it to pass behind the inwardly eX- tending flanges of the angledmembers 23.

Each end of the hood 24 has secured thereto a body of felt 26 whichwipes along the inner face of the adjacentframe member 1 to prei ventinsects from entering between the ends of the hood and the frame.

In Figures 4, 5, 6 and 7 where is shown a modified form of the structuredescribed in Figures 1, 2 and 3, there is provided a pair of screenroller brackets 27 each of which comprises a plate 28 having a reducedouter end 29 and carried upon an escutcheon plate 30. The plate 30 has arearwardly projecting centrally positioned lug formed upon the rear facethereof as indicated by the numeral 31 and this lug carries a securingplate 32 which is of greater width and less length than the escutcheonplate 30 as is clearly shown in Fig. 6.

One of the supporting plates 28 is provided with a notch 33 for thereception of one end of the screen roller 34 while the other plate isprovided with suitable apertures to receive the trunnion or pin (notshown) upon the other end of the screen-supporting roller.

The screen carried upon the roller 34 is indicated by the numeral 35.

Supported by and between the reduced portions 29 of the bracket plates28 is a roller 36 similar to the roller 12 employed in the preferredform and this roller performs the same function as the roller 12 in thepreferred form.

Connected to and supported by the escutcheon plates 30 is a hood 37 theupturned flange portion 38 of which extends across the outer' face ofthe window sash 39 to which the modified structure is attached. Themodified structure is also provided with thel felt 40 upon the ends oft-he hood 37 for the purpose described in connection with the preferredform.

In order to place the preferred structure in position upon the windowsash, the outer face of the sash at each side and adjacent the loweredge thereof is provided with a mortisef 41 over which a keeper plate 42is secured, this keeper plate being counter-sunk, in the face of thesash, as is clearly shown in Figures 4 and 5. The keeper plate 42 isprovided with a keyhole slot, the upper portion of which is relativelylarge and substantially square in configuration as indicated` by thenumeral 43 while the lower portion is con- Vstructed or relativelynarrow as indicated at 4-4, the upper end of the lower portion of theslot opening into the enlarged upper portion 43. When the keeper plates42 are in the position shown in Fig. 4, and it is desired to attach thescreen to the window sash, the two latch plates 32 are each extendedthrough the large portion 43 of a slot in a plate and Y then allowed todrop so that the stud 31 passes downwardly into the slot 44 thuspositioning the latch plates 32 behind the keeper plate 42.

A1n this manner, the screen roller and brackets are securely attached tothe window sash.

The lower portion of the screen structure 45 is the same as thestructure shown in Figs.

1, 2 and 3 inclusive and therefore needs no description with this form.The guide plate or angled member 45 is also like that used in connectionwith the preferred form.

From the foregoing description it will be readily seen that with awindow provided with a screen structure of the above-describedcharacter, the window will be screened at all times when the sash isopen and when the sash is closed or down the screen will be rolled andstored from sight thu-s making it possible to keep windowsclose-screened throughout the year without material damage to thescreen. With the structure shown in Figures 4 to 7 inclusive, the screenmay be readily attached or removed as desired thus enabling the user totake the screen ofi' at the end of the summer. The keeper plates 42being mounted in the outer face of the sash, will not interfere with'the raising or lowering of the sash when the upper sash of the windowframe is lowered and it will therefore be readily seen that the removingand replacing of the modified structure is extremely simple.

Having thus described my invention, what I claim is In a window screendevice, a vertical angle bar adapted to be secured to a window frame, ascreen roller supporting bracket adapted to be secured to a window sashand projecting forwardly therefrom toward the angle bar, and an idlerroller, one end of which is carried by the forward terminal of thebracket over which the screen is trained for urging the screen intoContact with the angle bar.

In testimony whereof I affix my signature.

CHARLES E. NICHOLSON.
